[libcxx-commits] [PATCH] D60880: [libc++] Use COPYFILE_CLONE from the macOS copyfile(3) API to support APFS clones

[Adrian Prantl via Phabricator via libcxx-commits]

aprantl added a comment.

According to the documentation COPYFILE_CLONE will clone a symlink rather than its contents, whereas COPY_FILE_DATA will follow the link. That's why I'm checking for symlinks in https://reviews.llvm.org/D60802. I don't know whether copy_file_impl_copyfile makes any guarantees.
